ADJUSTMENT PROCEDURES-5
Adjustment of laser power
[Preparation]
(2) Press the
JOG
button .
[Adjustment]
Digital volt meter
(1) Connect digital volt meter to I+3V and IOP on Extended JIG.
(2) Set the optical sensor to laser power meter.
(3) Loading of the optical sensor to the unit.
(3) Turn the
JOG
knob, adjust so that reading
of the laser power meter becomes
0.86 to 0.92mW.
[Note]
Do the work to (5)-(7) within 15 seconds.
Since continuation luminescence of the 7mW laser power is carried out, if it is left for a long time,
the pickup will deteriorate.
(6) Press the
JOG
knob.
(5) Turn the
JOG
knob, adjust so that reading
of the laser power meter becomes
6.9 to 7.1mW.

mechanism
(1) Turns the
JOG
knob, and select the
L D P W R A D J U S T
mode.
Check of laser power
(1) Press the
EDIT/NO
button .
(3) Press the
JOG
button .
(4) Checks that reading of laser power meter is
0.85mV to 0.91mW.
(6) Checks that reading of laser power meter is
6.9 mV to 7.1 mV.
(7) Read the value (
V
) of digital bolt meter.
(8) Press the
EDIT/NO
button after check.
(9) Press the
EJECT
button and takes out
the optical sensor
(10) Remove the digital volt meter from JIG.

(2) Turns the
JOG
knob, and select the
L D P W R C H E C K
mode.
(5) Press the
JOG
button .
Check that the laser current is
-10 to +10%
of range of the
display value of the pickup unit (Fig-1).
Calculate laser current
(I)
from the value(
V
).
I
(mA)
= V / 1
